HEEL-BUILDING MACHINE.

Application filed June 19, 1925. Serial No. 38,190.

My invention relates to heel building machines, and more particularly to a machine where lifts are selected and stacked in proper form for a particular style heel, each lift being. glued to the other, then the mass pressed into a homogeneous heel structure after which they are discharged from the 1na chine.

The invention is in the nature of a carry forward the patent granted to meMarch 2d, 192%. numbered 1,487,980. In said patout the lifts were assembled in proper formation and forced on a key by hand, as was the adhesive material, so as to form a particular style heel, after which manual means was employed to secure the initial pressure. The present invention is not only an improvement on all such means, but for a machine whereby its mechanism is simple, cheap and au omatic, thereby accomplishing a result with a better, more perfect and greater production.

An object of my invention is to have a central pedestal on which will revolve intermittingly a member, provided with a plurality of circumferentially arranged assembling devices adapted to receive on a means, a stack of selected lifts in superposed relation, each lift being glued one to the other, then applying pressure to the stacked mass before they are i'lischarged. The revolving member is given a step by step interi'nittent move ment, allowing only the necessary time for the operator to assemble the proper number of lifts to make the predetermined height heel. For instance, the machine has two sources of power, one to act upon the horirontally revolving member and the other for operating the vertically reciprocating lift assembling mechanism for stacking the lifts into mass formation of a proper height, first, the several lifts of various sizes to form a particular style heel are stacked and glued position on the key. second, the revolvable manner isthen moved a step when the stael; of lifts receive its necessary pressure At a pi*edetermined point the pressure is released, the presser foot raised, the hey extracted and thestack released from the equalizer, and y the built-up heel discharged from the asser ibling device. After which the key is again automatically moved in position and the iissembling device placed again in front of the operator to assemble another stack of hits to form a particular height heel.

Another object of my invention is, to pro vide a suitable number of heel assembling devices arranged about the circular revolvlng member, whereby the same will be in its ex tended position when it arrives in front ofthe operator. Each embling device receives a suitable number of selected lifts of various sizes and shapes for either a flat or inclined heel of a particular style and height, each lift not only being locked to the preceding one, but ach being in addition glued to the other lift, so as to form perfect heel of a predetermined style and height. Each and every time a mass of lifts have been assembled and glued in superimposed relation in the assembling device, each of the various preceding builtup heels are undergoing various processes in the contii'iuous production of the built-up heel while its revolving member is making a complete revolution.

Still another object of my invention is to provide a machine whereby the operator sits in front of the machine and has within his or her reach lifts of the various sizes to build heels of a given height and design, and after each built-up mass of lifts are stacked to the proper height-,the same is moved one step in its travel, as has been noted, to allow another empty assembling device to come before the operator. A calibrated scale is operated by the lift assembling mechanism, whereby the operator may see at a glance the particular height of the lifts that have been so far assembled.

With the foregoing and other objects in view, further objects and advantages will appear as the description of the invention is hereinafter (tlevcloped. I

Like characters of reference designates same parts throughout the several views of the drawings.

As is well known in the trade, some heels are nailed to hold the'various lifts that form the same in stack formation, in which case they cannot get the same pressure tothe lifts that may be applied to those that are glued, ecause of the fact, first, that if a full length nail is used, it will take the pressure that should be received by the various layers of lifts; or if the nail is too short, then the lifts will not all be held together in mass formation.

Again, should a heel be built by hand or by device in anything but a perfect manner, even should the imperfection be of a very slight degree, will, when it is placed in the compressor, be aligned all right; but in doing so, the glue that is holding the lifts together becomes cracked and broken, with the result that when taken from said compressor the heel will be defective, causing loss of time and labor.

The machine as constructed and operated comprises a central pedestal having thereon a stationary and a movable member, each member having coacting and cooperative parts that are brought into action by reason of the movable member being moved by the prime mover (not shown). hen the operator presses the lever 103 downwardly the link 152 is removed from the depression 153 in the stop cam 153. To the upper face of the cam is secured a ratchet and pawl mechanism 154, which operates the shaft 155, the latterhaving on its opposite end a gear 156 which meshes with a like gear 157 that is on the movable member 22. By pressing this lever 103 it starts the movable member on its degree of intermittent rotation. The motor being so geared to the movable member as to move it at the proper speed to allow the various cooperating devices to perform their respective operations while so moving. Again, the motor moves the movable member only as far as is required to bring the next assembling device in front of the operator. Then as the operator presents each lift to the key in the assembling device the lever 101 is pressed downwardly which causes the motor A to operate the heel cooperatin parts, causing each of the various devices connected therewith to perform their respective cooperative action until. the complete number of lifts have been assembled to form a heel.

My improved heel building machine coinprises a central pedestal 21, having a revolw able member 22, and a non-rotating member 23; the latter having a suitable hub 2 1, Wll'ill extending strengthening ribs 25. that provide a very strong resisting plate for the parts that cooperate therewith.

On the top of the pedestal 21 is a hand wheel 26, provided with suitable means for raising and lowering the non-rotating memill) til)

should move for a heel eta given height.

For instance, as shown particularly in Fig. *l 't' l--" lt ill iii/V it i, v ion 1 1s ccsnec o swirl w ieei c erg 1. hits, or 8 eighths, as termed 1n the trade, the

. 1 i 4. .1 7 4 2 is 1' (I hand beer as is ruined llnbll lire iucicarmg .iinger 2S registers on the scale for the 8 eighths.

By this means, the required adjustment is iii-ride to the non-rotating member, so that when the rotatable member ith. its assembling devices come under the various dc ices carried by said non-rotating member, that the he l carried therein will get the lesired pressure from the "evice.

Referring now to Fig. 1, wherein is shown my main operating device, it being under-. stood that a motor A provided with a start ing and braking mechanism will be placed on top of the non-rotating member The shaft 29, which carries a main driving cam 30 having a closed way 31 therein, and into which is fitted to operate a roller 32, carried by a vertically lQClPl'OCtited member 33 forming the upper part, and the lower part, which latter carries the mechanism for completing the building up oi the lifts into the heel. To the outer end of shaft 29 is a worm 29 enclosed within a casting 35, which also houses a suitable wheel 3 '3 shown in Figure 4; the shaft 86 of the latter is squared at its upper end so as to permit the carriage to be rcci irocated while the worm revolves the 7 shaft.

The reciprocative members 33 and are normally connected together by two rods 3? and 38, the latter making the full stroke of the upper member 33, while the lower member 34 is only resiliently secured. to the lower end of the rods 37 and 38, sprin-"gs 39 interposed between the member 84 and the collars 40, permits the member 34 to be arrested while the member 33 and rods 37 and 38 are making their full stroke.

Referring now to the receiving; devices into which the lifts are assembred, see Fig 4 and it will be seen, above noted, that the lower member 34 carries two li'it pressure fingers 41 and 42, which are adjustably secured to a movable slide 43, which may by reason of the hand wheel 44, be adjusted longitudinally so that the lingers press the lifts down as they are presented manually by the operator on the key 45. As the cam 30 causes the member 34 to reciprocate, the iinp ers and 42 do also; but as each lift is placed on the key 45, the fingers arrest the lower member 34 from further downward movement. As noted, as each lift is placed in posltion on the equali er, the men'iber 34 tends from the rod 37 to the rod 47, the for- 'mer causes the said bar to take the tall stroke 7 is arrested from further movement by the iingersfll and 42 resting on the top lift, the calibrated scale 46 carried by the lower member 34 is also arrested, while adjacent to the scale is a movable slidable bar 47, on which is securee an indicating member 48, operating over the -face of the scale 46. The counting or indicating device comprises a spherical chamber 48, tapering as it reaches its lower end, and into which is held a spring 7 49 that abuts against the screw 50, and against the ball 51. In addition to the above, an adjustable gauge 52 may be secured to the stationary member while the movable mem ber 48' carries a tooth 5:2 that is adapted so to engage the part 52, which parts are connected with the audible signal showing that the predetermined number oi li'l'ts have been applied. It will be seen, since an arm ex of the member 33, while the lifts placed in the receiving member arrest the scale, and the difference in the movements of each reg-is ters on the scale 46. Thus, for every hit that is placed on the key 45, the counting device just referred to will register the height the heel has been built. On the lower end 156 ot the bar 47 is a spring 157 which urges the member 48 upwardly to return the indicator member 48 to its normal position.

A handle is pivotally'arranged whereby, after each heel has been built to its desired height, the operator presses the handle and the indicating linger will return to zero.

The gumming device is one of the essential devices of my machine, and pres'i'nningr that the fluid is of the proper consistency for perfect operation, a reservoir is provided for holding a suitable quantity of the glue in a convenient place, so as to be fed to the machine in quantities as may be needed. iteiferring to Figs. 10 and 12, wherein is shown the gluing system detached from the oth cooperating parts, and its operation is follows: I

For every revolution of the shaf 39 the cam 30 will revolve the driving me to cause the shaft 36 to revolve. Said sha it carries a cam 53, that causes the lever [$4 to raise and lower at proper times. id lever is hinged to the top of the lower reciprocating member 34, in cars 55, and extends rear- \'\-'ardly and rests on the top ot'. a plunger rod 56, We latter haviii roller 5'? thereon, so as to 'e as little friction possible. The rod 56 passes through a sn'iall pump 58, which causes the glue to be forced from the source or supply through pipe 59, to a small. reservoirGO, where in turn it is forced through a flexible pipe Gl down to the brush. The latter is provided with a suitable receptacle ($2 for holding: a small quantity, and through openings 63 in the top of the brush 63, permits the fluid to saturate the bristles of the llu brush and thus the lifts when contact is made.

The operation of the brush is as follows: Referring to Fi gs. 8 to 13 inclusive, it will be seen as the cam causes the upper and lower reciprocating members and island their co-acting parts to descend, and as the shaft 36 revolves. it causes the cam 53 to revolve, at the same time cam 04, which is on the lower end of said shaft. Suitably mounted on a short shaft (55 is an arm (30, having at its'free end a roller 6?, to operate with the cam (36%, which arm operates a handle 68 having a latch 60, the latter being hinged at 70.

Secured to the shaft 65, below the handle 08, is a gear segment 71, loosely mounted on said shaft, which meshes with another gear segment 72 on a shaft'ili. The former ment is. provided with suitable actuating sprin Tel. to return the parts LO their proper position of rest after being operated. Said gear segment '71 has a body portion 75, which may he provided with a notch 76, or other equivalents, to receive the end of the latch 69, where it may be provided with a stop for the handle. The gear segment 72 has a. heel 7?, provided with a regulating screw 78 and a nut 79. so that the proper movement may be prov'icietl for the shaft 73, by its contact with the projection 80 on the lowermcmber 234:.

It will be understood thatwhcn the latch (39 in the notch 75, the segment '71 will opcrate s-iegment 72 on shaft '13. To the lower end thereof secured a lever 81, having a slot 82, which operates a pin'83, on a slide 8: carried by the member 34:. Thus, as said shaft is operated by the segments to force hose parts forward, the springs will return the same to their rearward or normal inoperative position. The slide 8%, which carrice the brush, on its extreme forward movement, moves the brush operating mechanism into contact witlran adjustable screw 85. see l ir'. t, held in a lug on the member 34-. Said s cw tri s the lever 80, mounted on a short spring pressed shaft 87, arried by the brush holder. On the lower side of the slide 8 f is a small bracket 88, which engages a hooked lever 89 on the shaftST. The brush holder has on each side an arm, 90 and 91, through which guide bars 92 a no extend and about the latter are preferably secured coiled springs 94; a ,d 95, held between the slide 84 and the arms 90 and 91. Thus it will be seen that as soon. as the arm 80 is tripped by the screw 85, the latch lever 89 will be released from the bracket 88, and the springs 9%.; and 95 will force the brush with its contei of glue down. At this point the brush when it is tripped is over the lift that has been forced down on the key by the fingers l1 and l2. Consequently when the brush 63 is lowered the lift is applied with paste, then as the arm 81 draws the slide 841 back,

it draws the brush with its adhesive mate rial across the top lift, and leaves thereon a deposit of glue for the next lift to be forced down upon. Thus when the brush is returned to its rearmost position the lever on the low side of the cam 53, and as it returns to'its position of rest, the lever 54; is depressed by the roller 57 riding up on the elevated side of the cam. In doing so, caus ing the shaft 56 to be depressed and thereby pressing on the free end of a lever 96 to elevate the brush (3?, the pivot 97 permits of the elevating and depressing of the brush.

Referring to Fig. l it will be seen that the reciprocating member 34- is provided with another dove-tail slide 98, whereby the tingers ll and 42 may be adjusted by a hand wheel 99 transversely of the member 3%, so that the fingers under any and all circumstances may be adjusted to their proper position with relation to the key 45, on which the lifts are held.

Each and every time the operator places a lift in position over the key 45, he or she presses a pedal 101 connecting by link 102, to the motor A on the non-rotating member. causing the cam 30 to revolve and the member 33 to reciprocate vertically onits guide bar 100, thus by this movement causing each cooperating part to function, and as has been seen, as each lift is selected and assembled in stack formation on the key 45, the member 3-l moves less and less vertically according to the number of lifts placed in the device. Each time the fingers 41 and l2 push a lift on the key 45, the heightthereof is registered on the scale 46 till the desired height of the heel has been stacked.

When the predetermined height of the heel has been reached the operator presses a pedal 103 and the revolvable member with the receiving device moves a predetermined distance by the power mechanism 10%, where the last filled receiving device is broughtunder the first of the pressure regulating devices on the 1'1()h1'()i7t1trtl)l.8 member, and is retained there while the operator is building the next heel. ()nly a part of the power mechanism is shown, and description thereof will be given further on.

Thus we have seen that the heel operating mechanism is entirely held stationary in front of the machine without interfering in any way with the revolvable member that carries the several assembling devices. The latter comprises a. breast plate 105, so curved to fit the breast of the heel and has on itsinner face the key 4:5, operating in. a way 106. Enid l. on its 10 781 end has a bearing rod 107, pass 9; through a. bearing 108; on the lower outer face of the breast plate. Said rod has a cam head 109, provided with a finger 110 that operates in the cam path between faces 111 and 112 the former being in the nature of a. closed cam, while the latter is simply a slide whereby the till finger forces the key back in proper position to again receive another stack of lifts. Said bearing 108 is also provided with a suitablspring 113, while the head 109 has a suitable recess into which said spring snaps and holds the key always in position till again operated upon by the cams 111 and 112.

Referring particularly to Figs. 2 and 3, it will be seen that the breast plate may be provided with a rearwardly extending base 114, having outwardly extending guide flanges 115 and 110, the latter being housed in the revolvable member 22. The base plate 114 near its forward end has a cut away part 117, and is provided with a slide having graduated steps 118. Said movable slide is adapted to be moved rearwardly when an inclined heel is desired. An equalizer 119 having a pointed forward end 120 that rests under the curved breast 106, which holds it in position, the under side of said equalizer is provided with a foot 121, to which may be secured one or more adjusting thumb nuts 122 for holding the equalizer in any predetermined position, according to the style of the heel to be built.

Said equalizer 119 may have any desired depth of plate 123 secured thereto, so as to give the heel a more or less cupped depression. Suitably securedto the base 114 is another bearing 124, extending from the assembling device, having a pin 125, operating therein. Said pin has a collar 126, which permits of its top being below the cupping plate 123, while its lower end is adapted to engage a stationary guide plate 127. Thus it will be seen from Figure 15, about the same time the key 45 is extracted from the built up stack of lifts, the plate 127 will cause the pin to move vertically and thereby elevate the built up heel slightly, thereby loosening the heel should any of the'glue have leaked over the lift to the'equalizer. B y soreleasing the-builtup heel from the equalizer, it will be an easy matter teen, the revolvable member turns to its n t position, for the kicker 128 to disloc go and discharge the same. To the pres sure member 23, is secured a liiracket 129, and pivoted to the latteris a kicker arm 130, pivoted to the bracket at 131, and provided. at its upper part with a slotted end 132, while the bracket .is provided with an ear 133, into which is housed one end of a rod 34, the other end extending through said slotted end 132 and having a head 135 thereon, while between the car on the bracket and the slotted end of the kicker arm is a suitable spring 136, that yieldingly engages the heel and discharges the same as the revolvable member pa es said kicker.

The revolvable member 22,

as is shown in Fig. 1, consists of two parts, one above the other, separated by suitable spacing arms 137. The lower part of the revolvable memher car es a plurality of receivingor assembling devices 105, while the upper part carerts upon it.

ries a presser foot 138, provided with a stem 139, passing through the upper part of the revolvable member, and is provided with wheel 140. The stem may be provided with a stop 141, so as to regulate its lowermost poion. in the face of the upper part of the revolvable member is a friction lock, comprising a curved face stud 142, having a leather or other suitable substance 143, between the same and the stem 139, while a screw 144 provides the proper pressure on the stem to hold it in any of the several positions it may asume by reason of coming in contact with the pressure c evices, that will now be described.

As soon as the proper height of lifts has been stacked in the receiving device to form a particular style heel, and the operator presses the pedal 101, the revolvable member starts and moves a predetermined distance or one step in its travel; as soon as it does, the wheel encounters the inclined block 145, which is suitably secured on its inclinedend by screw 146, while its inner end is provided with upwardly extending pivoted rod 147 passing through pressure plate 23, and through a collar 149 and a yoke 149, secured tothe top of said plate. Said rod has a suit able adjusting means 150 to regulate the downward pressure that the springs 151 ex- The nuts 150 with the yoke 149 regulates the spring pressure desired on a particular built-up heel.

The friction means on the stem 139 obviates the necessity of having a continuous pressure plate, which at all times would be in contact with the wheels 140., WVith my improved means, suitable pressure may be made with one device 145, or such blocks be arranged to give successive pressures to the heel as it passes thereunder.

Referring to Figs. 14 and 16, it will be seen how the pressure block presses the presser foot 130 down on the built-up mass, and after having passed the final pressure de vice 145, how the heel, by a further movement of the revolvable member, brings the roller 140 on its next step fromthe pressure block to the releasing cam 152, which is also secured to the under side of the pressure plate 23,,

and in path of the rollers 140. As the rollers nu footfrom the stack, the finger 110 is'trapped by the faces of bars 111 and 112 which then extracts the key from the stack, and one further movement by reason of the 'projec-. tion on the receiving device coming in contact with an outwardly extending cam 151', extending beneath the revolvable member, causes the IQCGlVll? devices to be extended to their extreme length, where it remains; and by a further movement the key is'again inserted in place for further building by the operator. 1 r

By reason of the edges of the key being made knife edged it is only necessary to make along this plate, lifting the'presserf Ill the key-way in the various lifts in the form of a notch, the fingers ll and 42 insuring the various lifts being forced down on the key, where they will be held against all pressures that may be exerted in any direction, without getting out of alignment. In other words, this machine builds heels of a predetermined style, in such alignment that when the product is placed in a mold that fits that particular heel, it is held therein while the final cupping is being formed. A type of heel. lift adapted for manipulation in my ma chine is shown in Figures 19 and. 20, and has a body 159 and akey notch 160.

Thus it will readily be seen that the employment of my machine or building heels will not only perform automatically what has heretofore. been done by hand, but will be able to perform the operations in a much more rapid rate, and much more effectively than has heretofore been done by hand.

From the foregoing it will be seen that l have provided a construction which is simple and effective, and whereby the lifts are not only assembled into a mass to form a heel, but that the mechanisms are all arranged to work automatically, following the method disclosed in my hereinbefore mentioned patent.

According to the provisions of the patent statutes, I have described the principle and operation of my invention, together with the construction which I now consider to be the best embodiment thereof. However, I desire to have it understood that the machine, as shown, is only illustrative and that the invention can be carried out in other ways than those described. As, for instance, it may be noted that an alarm may be provided so tha when the desired or predetermined height of the heel had been attained, that a hell would be sounded and thereby obviate the necessity of the operator watching the scale 46. at all times; or would be a means of attracting the attention of the operator at the particular time when the number of lifts had been stacked to the desired height.
